Minecraft VR Touch Controls

Despite the somewhat mixed reviews I've heard I am enjoying Minecraft Win 10 Edition on the Oculus... The biggest problem I have is the Left Analog Button being assigned to Immersive/Couch mode. I find myself flinching and accidentally pressing the button and then being unable to move for the next several seconds.

Has anyone discovered away to modify key bindings for this? Damn Microsoft and their inability to communicate things, or provide a responsive customer support base not to mention their obfuscation of simple settings.
